  Structure–Activity relationships of 6-fluoroquinazolines: dual-Acting compounds with inhibitory activities toward both TNF-α production and T cell proliferation

  摘要：

  We synthesized various 6-fluoro-7-(1-piperazino)quinazolines based on the structure of I and evaluated their inhibitory activities toward both TNF-alpha production and T cell proliferation responses. Among these compounds, 7a, having the 3,4-(methylenedioxy)phenyl moiety at the C(4)-position of the quinazoline ring, showed both inhibitory activities. Furthermore, the oral treatment with 7a exhibited an anti-inflammatory effect in rats with adjuvant arthritis as well as an inhibitory activity toward LPS-induced TNF-alpha production.
